<p>PROBLEM TO BE SOLVED: To facilitate overtime calculation by providing a 1st cursor of length of basic work time and a 2nd cursor which is graduated with overtime. SOLUTION: A main body part 2 is continuously graduated with time, and time gradations are given on the surface of the 1st cursor fitted slidably in slide grooves 2a and 2b; and the time gradations are given from the zero gradation at the left end and the basic work time is represented at the left end. The 2nd cursor 4 which is inserted into the 1st cursor 3 so that it can be drawn out of the right end of the 1st cursor 3 is also graduated with time, and the time gradations represent overtime, and are given successively in order. The zero gradation at the left end of the 1st cursor 3 is positioned at 8:45 (work start time) of a time gradation of the main body part 2, the zero gradation of the 2nd cursor 4 is positioned at 21:00 (company leaving time) of the main body part 2 and the time gradation of the 2nd cursor 4 indicated at the right end of the 1st cursor 3 is read.</p> |
